MIC5249  
300mA µCap LDO with  
Programmable Power-On Reset Delay  
General Description  
Features  
The MIC5249 is an efficient, precise 300mA CMOS  
voltage regulator with power on reset (POR) delay which  
can be implemented via an external capacitor. It offers 1%  
initial accuracy, extremely low dropout voltage (typically  
400mV @ 300mA), and low ground current (typically  
85mA) over load.  
300mA output current  
High PSRR: 65dB@120Hz  
Stable with ceramic output capacitor  
Power-on-Reset (POR) output with adjustable delay  
time  
High output accuracy:  
Designed specifically for noise-critical applications in hand-  
held or battery-powered devices, the MIC5249 comes  
equipped with a noise reduction feature to filter the output  
noise via an external capacitor. Other features of the  
MIC5249 include a logic-compatible enable pin, current  
limit, thermal shutdown, ultra-fast transient response, and  
an active clamp to speed up device turnoff.  
±1.0% initial accuracy  
±3.0% over temperature  
Low dropout voltage of 340mV @ 300mA  
Low quiescent current: 85µA  
Zero current shutdown mode  
Thermal-shutdown and current-limit protection  
Tiny MSOP-8 package  
The MIC5249 also works with low-ESR ceramic  
capacitors, reducing the amount of board space necessary  
for power applications, critical in hand-held wireless  
devices.  
Applications  
The MIC5249 is available in the MSOP-8 package.  
Cellular phones  
PDAs  
Fiber optic modules
